スが用いられて来た。As a method for producing soda-lime glass for fluorescent lamps, a reduction melting method and an oxidation melting method have been conventionally known. Among them, the oxidative melting method uses arsenic for glass production, and is therefore unsuitable for mass production because it may cause pollution by arsenic, and soda lime glass by the reduction melting method has been used exclusively.

ことを目的とする。INDUSTRIAL APPLICABILITY The present invention has clarified the necessary conditions for stably producing a brighter fluorescent lamp using soda-lime glass manufactured by the oxidation melting method than a lamp using soda-lime glass by the conventional reduction melting method. The purpose is to be able to supply a fluorescent lamp brighter than before.

率を65％以上に限定したものである。In order to solve such a problem, the present inventors have conducted various research and studies, and as a result, when a fluorescent lamp bulb is made of soda-lime glass by an oxidation melting method, the infrared transmittance of the glass is the brightness of the lamp. However, as a result of research, the infrared transmittance per mm of the wall thickness is limited to 65% or more.

透過率を65％以上に限定した。The soda-lime glass fluorescent lamp manufactured by the oxidation melting method, which has an infrared transmittance of 65% or more per 1 mm of wall thickness, is much brighter than the soda-lime glass fluorescent lamp manufactured by the reduction melting method, which has the same visible transmittance. Then, the ratio of the actual brightness divided by the brightness calculated from the visible light transmittance of the soda-lime glass fluorescent lamp by the oxidative melting method, based on the soda-lime glass fluorescent lamp by the reduction melting method (luminous flux ratio) When the infrared transmittance is 65% or more, the luminous flux ratio is larger than 1 and the larger the infrared transmittance is, the larger the infrared transmittance is. Therefore, the infrared transmittance is limited to 65% or more as described above.
（第１図参照） 〔実施例〕 還元溶融法によるソーダ石灰ガラスを仮りにＡガラス、

すれば、両ガラスとも基本組成は下記の第１表のとおり
共通で酸化アンチモン(Sb2O3)の混入量が若干異なる。(See FIG. 1) [Example] Soda lime glass by the reduction melting method is temporarily assumed to be A glass,
If soda lime glass produced by the oxidative melting method is changed to B glass, both glasses have the same basic composition as shown in Table 1 below, and the mixed amount of antimony oxide (Sb 2 O 3 ) is slightly different.

(α) is shown in Table 2 below.

Fig. 2 shows the spectral visible light transmittance when it is 6% by weight.
The spectral infrared transmittance is shown in FIG. In each of these figures, the horizontal axis is the wavelength in mm and the vertical axis is the transmittance in%. The curves (A 2 ) and (B 2 ) in FIG. The spectral visible light transmittance curves of B glass and B glass, and the curves (A 3 ) and (B 3 ) in FIG. 3 show spectral infrared transmittance curves of A glass and B glass, respectively. From these figures, it is understood that B glass has a high transmittance for long-wavelength visible light and infrared light.

示す。Next, using A glass and B glass containing 0.06% by weight of Fe 2 O 3 and different phosphors to form a ring-shaped fluorescent lamp, the brightness at the initial stage of lighting was investigated. The results are shown in Table 3.

過率が何んらかの影響をしていることを示唆する。 As is clear from Table 3, the B glass fluorescent lamp is much brighter than the A glass fluorescent lamp, and the difference is much larger than the effect (calculated value) due to the difference in visible light transmittance. Further, the exceptional brightness of the B glass fluorescent lamp is particularly remarkable in the case of a fluorescent lamp having a red light emitting phosphor such as FCL30 / 28EX and FCL30 / 28W. This suggests that the infrared transmittance has some influence on the brightness of the B glass fluorescent lamp.

を65％以上に限定した。Therefore, the above-mentioned FCL30 / 28W-F was produced using various B glasses having different infrared ray transmission rates, and the influence of the infrared ray transmission rate on the brightness was investigated. The results are shown in FIG. In the figure, the horizontal axis is the total transmittance of 1 nm of thickness of all infrared rays with wavelengths of 800 nm or more in units of%, and the vertical axis is the luminous flux, that is, the ratio between the above-mentioned actual brightness and the calculated value. The curve shows the correlation. As is apparent from FIG. 1, the luminous flux ratio becomes larger than 1.00 when the infrared transmittance is 65% or more. In other words, when the infrared transmittance of B glass is 65% or more,
The actual brightness of the fluorescent lamp became brighter than the brightness calculated from the visible light transmittance, and an unexpected improvement effect was obtained. Therefore, in the present invention, the infrared transmittance of the B glass is limited to 65% or more.

を次の第４表に示す。Next, it was investigated how the above-mentioned ring fluorescent lamp FCL30 / 28WF and the straight tube fluorescent lamp FL20WF affect the initial brightness of lighting by glass. The results are shown in Table 4 below.

して、環形計蛍光ランプは曲性工程において過酷な加熱
処理を加えられても劣化が少ないためと思われる。 As is clear from Table 4, the effect of the present invention can be understood to be more remarkable in the ring shape than in the straight tube shape. The reason for this seems to be that the ring-shaped meter fluorescent lamp is less deteriorated even when subjected to severe heat treatment in the bending process.

In the figure, the horizontal axis is the lighting time in hr × 100 3 and the vertical axis is the output in relative values. Curve A 4 is A glass, curve B 4
Shows the working characteristics of each lamp when B glass is used. From this figure, it can be understood that the working characteristics of the B glass fluorescent lamp are excellent.

A lamp that can be used exceptionally well beyond the expected brightness of the lamp from the light transmittance was obtained. Thus, the present invention is particularly effective in a non-linear fluorescent lamp that requires a heating bending process.
